Abstract

In this research, a microstrip patch antenna was designed for high-speed data transmission at 5G using millimeter waves (mm waves) in the frequency range of 40 to 75 GHz (V band). The suggested antenna has been developed with an operating frequency of 46.44 GHz. Research on the 5G Band, which spans the frequency range of 45.5 to 52.6 GHz is still in its early stages. Like all other millimeter wave bands 45.5 to 52.6 GHz band is also designed for transmitting and receiving data across short distances at high speeds. The proposed antenna is on a Roggers 5880 substrate that is 0.5 millimeters thick. The dielectric constant of the substrate is 2.3, and the loss tangent is 0.0009. The projected antenna has a gain of 6.1 dBi and a directivity of 6.7 dBi for a single element, and it has a wideband characteristic of roughly 4.5 GHz. The VSWR is 1.0019, and the return loss is somewhat significant at -60 dB (s11), however, the overall efficiency is 91%. The fact that the suggested antenna has good impedance matching, bandwidth, high gain, high return loss, radiation characteristics at the working band, and a compact and tiny size confirms that it is acceptable for use in 5G mm-wave applications.
